Determime whether each of the following is a prime or composite number
mr_godi [17]
Hi! Since prime numbers only have 1 and themselves as factors, 101 would be prime. 123 has factors of 1,3,41,123, so it would classify as a composite number. I hope this helps!:)

50 POINTS<br><br>Need help with these 3 questions. ​
mr_godi [17]

Answer:

1st: 1/x (6mins). 2nd: 12. 1 day.

Step-by-step explanation:

1st:

One person can do a certain job in ten minutes, and another person can do the same job in fifteen minutes. How many minutes will they take to do the job together?

One person's rate:: 1/10 job/hr

Other person's rate:: 1/15 job/hr

Together rate:: 1/x job/hr

If x represents how many minutes to do the job together, then how much of the job does the slowest person do? 6 minutes.

-------------------

2nd:

Given : The sum of one-third of a number and three-fourths of the number exceeds that number by one.

To find : Which equation could be used to find the number

Let a number  = n

One third of a number = .

Three - fourths of the number  =  .

Sum of their is  exceeds that number by one.

+  = n +1.

Taking common denominator

= n+1 .

= n+1.

On subtracting n both sides.

-n = 1

Taking common denominator

= 1

= 1

On multiplying by 12 both sides

n= 12.

-------------------

3rd:

Person A can finish job in 6 days

Person B can finish job in 2 days

Person C can finish job in 3 days.

So let us present it this way.

x/6 + x/2 + x/3 = number of days

Find common denominator which is 6.

x/6 +3x/6 + 2x/6 = days

6x/6 = days

x = 1 day.
